PRIORITY CLAIM

This application is a continuation of, and claims priority to, U.S. patent application Ser. No. 11/392,079, filed on Mar. 29, 2006, which is hereby incorporated by reference in its entirety.

FIELD OF THE DISCLOSURE

The present disclosure is generally related to processing multimedia data received via a network.

BACKGROUND

Closed-captioning (CC) refers to visual captioning on a video display that superimposes subtitles onto the display. “Captions” aim to describe all significant audio content, as well as “non-speech information,” such as the identity of speakers and their manner of speaking Additionally, captions may indicate sounds other than dialog that are associated with an aspect of the video. In many broadcast applications, closed-captioning information is embedded within the broadcast signal for decoding and for display along with selected video content of the broadcast signal. The term “closed” in closed-captioning refers to the selective display of captions for only those who decode or activate them. This is distinguished from open captions, where the captions are visible to all viewers.

For live programs, spoken words included in the program's soundtrack may be transcribed by an operator, and the phonetic output can be translated into text and displayed on the screen. In some instances, the transcript may be available in advance of the broadcast, and the captions may be displayed from the available transcript information. For prerecorded programs and home videos, the audio may be transcribed and the captions can be prepared, positioned, and timed in advance.

For National Television Systems Committee (NTSC) programming, the captions are “encoded” into Line 21 of the vertical blanking interval, which is a part of the broadcast picture that is positioned above the visible portion of the picture. For the Advanced Television Systems Committee (ATSC) programming, which includes digital or high-definition broadcasts, three streams are encoded in the video: two are backward compatible Line 21 captions, and the third is a set of up to 63 additional caption streams encoded in an Electronic Industries Alliance (EIA) format, the EIA-708 format. In countries that utilize a phase-alternating line or Systeme Electronique Couleur Avec Memoire (SECAM) programming formats, where teletext is used rather than Line 21, the captions are transmitted within the broadcast stream, but using a different method.

In the United States, since the passage of the Television Decoder Circuitry Act in 1990, manufacturers of most television receivers have been required to include a closed-captioning decoder to decode the captions from the broadcast signal and to provide the decoded captions for superimposed display, when closed-captioning is enabled. For older televisions that do not include a closed-captioning decoder, a set-top box or other external decoder may be required to provide closed-captioning.

NTSC DVDs may carry closed captions in the Line 21 format which are automatically sent to the TV and turned on and off by the TV remote or the set-top decoder. Video DVDs may carry closed captions as a bitmap overlay, which can be turned on and off via the DVD player.

Recently, as more consumers have subscribed to residential broadband Internet access, users are spending increasing amounts of time browsing the Internet at home, often while watching television. However, unless closed-captioning is turned on, the consumer may miss information available via the URL data within the closed-captioning information.

DETAILED DESCRIPTION

In general, web site information, such as a uniform resource locator (URL), may be included in closed-captioning information from a video broadcast source as part of the broadcast signal. A set-top box is coupled to the video broadcast source via a network and is adapted to decode the closed-captioning information, to extract the URL data, and to store the URL data in a memory. The URL data may be stored in a text-based file, which may be either formatted or unformatted. The set-top box may be adapted to generate a web page including the URL data for later retrieval by a user. Additionally, the set-top box may be adapted to organize the extracted information according to a retrieval date, according to an alphabetical order, according to subject categories, or based on some other user-specified organization.

A method and a system are provided. In one embodiment, a method includes receiving at a set-top box a broadcast signal including closed-captioning content, where the closed-captioning content includes subtitles related to the broadcast signal and uniform resource locator (URL) data. The URL data is extracted from the closed-captioning content. The URL data is stored in a memory of the set-top box.

In another embodiment, a set-top box includes a memory, a receiver interface, a closed-captioning decoder, and a URL parser. The receiver interface receives a broadcast signal. The closed-captioning decoder accesses closed-captioning information including URL data from the broadcast signal and to produce an American Standard Code for Information Interchange (ASCII) character stream. The URL parser extracts the URL data from the ASCII character stream and stores the URL data in the memory.

In another embodiment, a set-top box includes a memory, a closed-captioning decoder, a processor, and a web server. The memory is adapted to store Uniform Resource Locator (URL) data. The closed-captioning decoder is adapted to retrieve closed-captioning information from a broadcast signal to produce decoded data. The processor is adapted to extract URL data from the decoded data and to store the URL data in the memory. The web server has access to the memory to generate a web page comprised of the URL data.

In another embodiment, a processor readable medium embodying processor readable instructions is provided to decode a signal to produce uniform resource locator (URL) data. The processor readable instructions include instructions to decode a broadcast signal including closed-captioning information and associated URL data to produce an American Standard Code for Information Interchange (ASCII) character stream, instructions to retrieve the URL data from the ASCII character stream, instructions to store the URL data in a memory, and instructions to generate a web page including the URL data.

In another embodiment, a method is provided. A broadcast signal is received from a video broadcasting network at a set top-box. The broadcast signal includes closed-captioning content including subtitles related to the broadcast signal and uniform resource locator (URL) data related to an address of a web site. The URL data is extracted from the closed-captioning content. The URL data is stored in a database of the set-top box.

FIG. 1 is a block diagram of an illustrative embodiment of a system 100 for extracting selected data from closed-captioning information of a broadcast signal including a set top box with a closed-captioning decoder. The system 100 includes a set-top box 102 and a video broadcast source 104 coupled by a network 106. The set-top box 102 includes a closed-captioning decoder 110, a memory 112, and a web server 114. The set-top box 102 may be connected to a display device 108, such as a television. The web server 114 may be enabled to connect to a processing device, such as a portable computer 116 via a home network 118 (wired or wireless), and may be further enabled to provide routing services to connect the portable computer 116 to an Internet service provider (ISP) 120 via a wide area network 122, such as a public switched telephone network.

In operation, the video broadcast source 104 transmits a broadcast signal, including video data, audio data, and closed-captioning information via the network 106. The closed-captioning information may include uniform resource locator (URL) data. The set-top box 102 receives the broadcast signal from the network 106 and provides the broadcast signal to the television 108, which decodes the broadcast signal for display. In some instances, the television 108 may not include circuitry to decode the broadcast signal, in which case the set-top box may decode the video signal and provide the decoded video to the television 108 for display.

Additionally, the set-top box 102 decodes and extracts or retrieves URL data from the closed-captioning information of a channel being viewed, and stores the URL data in the memory 112. Alternatively, the set-top box 102 may be adapted to store the URL data in a memory of the portable computer 116 or of another device (not shown) on the home network 118. The web server 114 may be adapted to generate and serve a web page including the URL data from the memory 112 for access by the portable computer 116 via the home network 118. A user may access the web page and select links from the web page. The web server 114 is adapted to route access requests to the ISP 120 via the wide area network 122.

Advantageously, by storing the URL data in memory 112, the set-top box 102 preserves the URL data until the user is ready to view it. Moreover, advertiser information and other data contained within the broadcast signal may be decoded and stored for later viewing and use by a user.

FIG. 2 is an expanded block diagram of a particular embodiment of a set top box 102 adapted to extract URL data from closed-captioning information of a broadcast signal. The set-top box 102 includes an input interface 202, an output interface 204, a closed-captioning (CC) decoder 110, a memory 112, a web server 114, a uniform resource locator (URL) processor 206, URL data 208, a wide area network (WAN) interface 210, a local area network (LAN) interface 212, and a processor 214.

The web server 114 includes an input connected to the memory, an output connected to the WAN interface 210 and an output connected to the LAN interface 212. The web server 114 may be coupled to the processor 214 to process the URL data 208 from the memory 112 and to generate a web page containing the URL data 208. The web server 114 may provide the web page to a user via the LAN interface 212. Additionally, the web server 114 and/or the set-top box 102 may provide switching/routing services to route user access requests to the web server 114 or to the WAN interface 210 to access local data or to access data from the Wide Area Network, such as the Internet.

In operation, the input interface 202 of the set-top box 102 receives the broadcast signal from the network 106. The input interface 202 provides the broadcast signal to the output interface 204. In one embodiment, the output interface 204 may include a decoder to decode the broadcast signal. The input interface 202 also provides the broadcast signal to the CC decoder 110. The CC decoder decodes the closed-captioning information of the broadcast signal and provides the decoded information to the URL processor 206, which extracts the URL data from the closed-captioning information and stores the URL data 208 in the memory 112. The web server 114 generates a web page that includes the URL data 208 from the memory and allows a user to access the web page via the LAN interface 212. In one embodiment, the URL data 208 within the web page is displayed as user-selectable links that direct the user to a web page corresponding to the selected URL data. The user may select a link and the set-top box 102 may route the user to the WAN interface 210 for access to the selected URL via the Internet.

Alternatively, the display interface 528 may include a liquid crystal display or other type of viewing screen to display information to a user.

In general, the database 508 represents a data structure that facilitates rapid access to data and that supports insert functions, update functions, delete functions. Additionally, the database 508 allows for rapid changes to data. The database 508 includes, but is not limited to, indexed sequential access method (ISAM) files, binary files, flat files, relational database management systems, or any other type of data storage structure.

In operation, the signal input interface 504 of the set-top box 102 receives a broadcast signal from the network 106. The signal input interface 504 provides at least a portion of the broadcast signal to the video/audio output interface 506 and to the CC decoder 110. The video/audio output interface 506 provides a signal to the display or television 108, which produces a display 302 including the closed-captioning information 304. The CC decoder 110 decodes the closed-captioning information contained within the broadcast signal and provides the decoded closed-captioning information to the URL processor 206. The CC decoder may also provide the decoded closed-captioning information to the video/output interface 506.

The URL processor 206 extracts the URL data from the closed-captioning information and stores the URL data in the memory 112, such as within a data file or database 508. Additionally, the URL processor 206 may provide the information to the web server 114. The web server 114 is adapted to access the database 508 to retrieve URL data and to dynamically generate a web page containing the URL data. The web server 114 may provide the web page to the network transceiver 510 in response to receiving a request from the client device 520 via the home network 120.

Additionally, the set-top box 102 may include control logic 512, which may be coupled to a memory including user settings 514 and to the web server 114. The control logic 512 may provide control signals to the web server 114 to control when the web server 114 provides the web page, as well as how the web page is organized. The user settings 514 may specify a user organizational preference, such as a date order, a subject matter order, an alphabetical order, and so on. The web server 114 may generate the web page including the URL data organized according to the user settings 514 in response to control signals received from the control logic 512. In alternative embodiment, the web server 114 may access the user settings 514.

The processor of the client device 520 may execute processor readable instructions embodying the Internet browser application 530 from the memory 526, including a plug in or client application. The Internet browser application 530 may generate a request to the web server 114 to access the web page, and the web server 114 may generate the web page from the URL data stored in the database 508 in response to the request. Alternatively, the user settings 514 may specify that the user desires to have the URL page delivered automatically by the web server 114 in response to the addition of new URL data from the closed-captioning information. In such an instance, the web server 114 may interact with a plug in or client application 532 of the client device 520 to cause the Internet browser application 530 to initiate the request to the web server 114 or to retrieve and display the web page.

Depending on user preferences defined within the user settings 514, the web server 114 may passively serve a web page in response to access requests or may actively push the web page to a client device for display.

 2. The method of claim 1, wherein the memory of the set-top box includes a database and wherein the uniform resource locator data is stored in the database.
 3. The method of claim 2, wherein the web page includes a second selectable option to enable the uniform resource locator data that corresponds to each selectable link associated with the checked check box to be removed from the database.
 4. The method of claim 1, wherein extracting the uniform resource locator data comprises: decoding the closed-captioning content into an American standard code for information interchange character stream; and parsing the American standard code for information interchange character stream to retrieve the uniform resource locator data.
 5. The method of claim 1, wherein the device comprises a computer.
 6. The method of claim 1, further comprising sending a processed portion of the broadcast signal for display at a display device coupled to the set-top box.
 7. A set-top box comprising: a closed-captioning decoder to produce decoded data from closed-captioning information of a broadcast signal; a first processor to: extract uniform resource locator data from the decoded data; and a second processor to: receive, via a user interface, settings related to an organizational preference from a client device coupled to the set-top box, wherein the organizational preference indicates a date order, a subject matter order, an alphabetical order, or a combination thereof; store the settings at a memory of the set-top box; and generate a web page including selectable links associated with the uniform resource locator data, wherein the web page includes a check box associated with each of the selectable links and a selectable option to enable each selectable link associated with a checked check box to be added to a uniform resource locator address book, and wherein the selectable links are organized according to the organizational preference; and a web server to send the web page to the client device via a local area network interface in response to a request received by the set-top box from the client device, wherein a user setting enables the web server to push the web page to the client device.
 8. The set-top box of claim 7, wherein the organizational preference indicates that the selectable links of the web page are to be organized by date.
 9. The set-top box of claim 7, wherein the organizational preference indicates that the selectable links of the web page are to be organized by program identifiers associated with the closed-captioning information.
 10. The set-top box of claim 7, wherein the closed-captioning decoder is configured to decode the closed-captioning information to produce an American standard code for information interchange character stream, and wherein the first processor is configured to parse the American standard code for information interchange character stream to extract the uniform resource locator data.
 11. The set-top box of claim 7, wherein the web server is adapted to provide the client device a second website, wherein the second website includes the user interface.
 12. The set-top box of claim 7, wherein the client device comprises a laptop computer.
 13. The set-top box of claim 7, wherein the web page includes a second selectable option to enable each selectable link associated with the checked check box to be removed from the web page.
 14. A computer readable storage device storing instruction that, when executed by a processor, cause the processor to perform operations comprising: decoding a broadcast signal including closed-captioning information and associated uniform resource locator data to produce an American standard code for information interchange character stream; retrieving uniform resource locator data from the American standard code for information interchange character stream, wherein the uniform resource locator data relates to a public service announcement; receiving, via a user interface, settings related to an organizational preference from a client device coupled to a set-top box, wherein the organizational preference indicates a date order, a subject matter order, an alphabetical order, or a combination thereof; storing the settings at a memory of the set-top box; and generating a web page that includes selectable links based on the uniform resource locator data, wherein the web page includes a first selectable option to enable each selectable link associated with a checked check box to be removed from the web page, and wherein the selectable links are organized according to the organizational preference; and sending the web page to the client device, distinct from the storage device, coupled to the processor in response to a request received from the client device, wherein a user setting enables the processor to push the web page to the client device.
